CUTTER BOARD.

Application filed. November invention relates to a board designed elements any metal or other hard substance likely to dull the edge or edges of the cutting tool.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodlment of the, invention herein disclosed may be made "plug 6 is forced into the opening 5 so as to within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings, the preferred form of the invention has been shown.

In said drawings, Figure 1 is a plan view of the device, a portion being broken away.

Figure 2 is a section on line 2--2 of Figure 1, the plug being shown in elevation.

Referring to the figures by characters of' reference 1 designates a plurality of segmental blocks each of which is formed, in its outer edge, with a'central groove 2 eX- tending from one side edge to the other of the block so that, when the several blocks arev assembled about a common center and in contact with each otherythese grooves will register to form an annular groove.

One of the blocks, which has been indicated at 3, is formed of two superposed sections resting flat upon each other and these sections have matching portions 4 cooperating to produce a portion of the circumferential groove heretofore referred to.

Then all of the sections are assembled they fit tightly together and produce a circular board. The inner ends of the sections also define a circular opening 5 the wall of which is screw threaded so as to receive a screw threaded plug 6 of wood or other material corresponding with that of whichthe sections 1 are formed.

In assembling the parts of the board a 11, 1925. ,Ser-ial at. eases.

metalring. 7 is first provided, this ring havk ing its ends welded together and, thev outer periphery of the ring being flat while the innen perlphery thereof is rounded; In

7 other words the material of whichthe ring is formed is substantially semi-circular in cross section as I shown. The various segmental, sections 1. are placed within the space surrounded by the ring and are positioned as close to the center of the ring as possible.

lhey are then shifted outwardly radially until the grooves 52 therein receive the ring 7. By pressing these segments together a segmental space will beleft between two of them, this space being just large enough to receive the split section 3. The members of this split section are placed in position. above and below the ring and are glued together or otherwise fastened, thus completing the circular board. As a means for holding the segmental sections assembled with theiring so that they will not become jarred or out of place when the board is in use, the screw engage the threads upon all of the segmental sections of the board, thereby anchoring the will be extended substantially in a circle about the center of the board and the segments are not likely to be chipped in use.

What is claimed is:

1. In a cutter board the combinationwith a ring, of se mental strips having registering grooves in their outer endsrfor the recep-P tion of the ring, a split segmental strip including superposed sections straddling the ring at the outer end and filling the space provided between two of the first named sections, and an anchoring plug inserted between the inner ends of the sections.

2. In a cutter board the combination with a ring, of'one-piece segmental sections in the space surrounded by the ring and having grooves in their outer ends in which the ring is seated, said sections being in contact except between two of the sections, ,a segmental section comprising superposed portions interposed between the spaced onepiece sections and cooperating to provide a groove for the reception of the ring, all of said' sections cooperating to provide an unbroken surface extending around a central opening, and a plug fitted snugly Within said opening for anchoring together the in- I i ne-r ends of all of the segmentalsections.

3. In a cutter board the combination With a ring, of one-piece segmental sections in the space surrounded by the ring and having grooves in their outer endsin which the ring is seated, saidsections being in contact except and cooperating to provide a groove for the reception of the ring, all of said sections cooperating to provide an unbroken surface extending around a central opening, and a plug fitted snugly Within said opening for anchoring together the inner ends of all of the segmental sections, said plug being'screw threaded and there being threads upon the inner ends of the sections for engagement With the plug,'the ends of the plug being flush with corresponding faces ofthe sections.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature.
